Abstract
To minimize the risk of damaging an internal oil passage for conducting oil, the lower structure of an internal combustion engine includes a bottom wall (6), a side wall (7) provided along a peripheral edge of the bottom wall to define the oil chamber in cooperation with the bottom wall, a device mounting seat (52) provided on the side wall and configure to have a prescribed device (51) attached thereto; and an oil passage portion (57) formed in the side wall to define the oil passage (56), wherein the oil passage opens at the device mounting seat, and a part of the side wall adjacent to the oil passage portion is provided with a load absorbing portion (61) configured to be more readily deformable than the oil passage portion.
